Study the following diagram and answer questions based on it.
The ratio of total number of train travelers to the people who do not travel by train is
Total number of train travelers = 100 + 10 + 20 + 50 + 50 + 50 + 100 = 380
Number of people who do not travel with train = 100 + 40 + 20 = 160
Required ratio = 380 : 160 = 38 : 16.
